Abstract
Un feu de véhicule (1) comprend une source de lumière (12a à 12d) pour dessiner sur un revêtement routier configurée pour émettre une lumière devenant une image de source de lumière, et une lentille de projection (20), qui a un axe optique s'étendant dans une direction avant-arrière et à travers laquelle la lumière doit passer. Le feu de véhicule (1) peut former une pluralité de motifs de distribution de lumière sur un revêtement routier dans une plage d'une position proche du feu à une position à distance du feu par la lumière émise à partir de la source de lumière (12a à 12d) et qui est passée à travers la lentille de projection (20), et les motifs de distribution de lumière respectifs doivent être projetés sur le revêtement routier dans des états où les positions relatives de la lentille de projection (20) et de l'image de source de lumière sont différentes.A vehicle light (1) comprises a light source (12a to 12d) for drawing on a road surface configured to emit light becoming an image of a light source, and a projection lens (20), which has an optical axis extending in a front-to-back direction and through which light must pass. The vehicle light (1) can form a plurality of light distribution patterns on a road surface in a range from a position close to the light to a position away from the light by the light emitted from the light source ( 12a to 12d) and which has passed through the projection lens (20), and the respective light distribution patterns are to be projected onto the road surface in states where the relative positions of the projection lens (20) and the light source image are different.
